I just moved up to the Composer from the 3G for the Optics.
I used it this week-end and had some issues that maybe someone can help with. With the 3G on a tripod, you could compress or push the bellows to get the sweet spot sharp, then fine tune. With the Composer it seemed that you have to move the whole tripod. Is there another trick to help or is the Composer made for more hand holding shots?
